' V AUTOMATIC TRAFFIC REGULATOR.

Application led April- 20,

To all whom it mag/concern:

Be it known that I, FRANK J. HUsBANns, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Automatic Traiic Regulators, vof whi'chthe following is a specification.

This invention isa traiiic regulator providing a' signal at points of traiic intersection, the signals for the respective points of traffic intersection being veither inde,- pendently locally controlled orsimultaneously controlled from a central station, and the central station controlling means being arranged to automatically give a signal for movement of'k traliic in the respective cross directions at the points of traiiic intersection atregular intervals.

It is the object ofthe invention to provide atratic regulator of this character having means for selectively giving a signal for movement of trailic in all directions at a point l` of trailic intersection, for iving a signalto stop traffic in all directions at said point, or for giving a signal for movement of traffic in one of the cross directions at said point and for stopping the traiic in the other `direction at said point, the selective controlling means being either independl ently locally actuated at the respectivef;A points of traffic intersection or automatically actuated from a central station.

In ractice it has been found necessary that t e traiiic regulator operate to give a signal for movement of traiic in all directions at a point of traiiic intersection during certain periods and particularly at night when the traiiic is practically negligible. Further, it is also necessary to provide a traiiic regulator for giving a signal to stop traiiic in all directions at a point of intersection in order to prevent movement of traiiic when an ambulance or similar form of emergency vehicle is 4 traversingl the streets.

Other objects of the invention will be readily understood from the following description of the accompanying drawings in which;

Figure l is a front elevation of one ot the signalling units partly broken away.

Fig. 2 is a longitudinal section through the same taken on the line 2'r-2 of Fig. 1.

1920. Serial No. 375,374.

Fig. 3 is a transverse section on the lline 3 3 of Fig. 2.

Fig. 4 is a diagrammatic showing of several points of traiiic intersection such as intersectingv streets, units of the improved traiiic `regulator being positioned at the points of traiiic intersectiom Fig. 5 is an enlarged plan view of the automatic controlling means employed in f 'ingsof a traiiic regulator and its local controlling means showing different controlling positions of the controlling means.

Figs. 11, 12, 13 and 14 are diagrammatic showings of a trafiic regulator and the cen- `tral station controlling means therefor, said controlling means being shown in the various controlling positions. i

The improved traiiic regulator is illustrated as employed in connection with points of traiic intersection as shown in Fig. 4 in,v

which parallel streets or roads are shown at A and parallel cross streets or roads are shown at B. One of the signalling units 0I" the traiic regulator is positioned at each corner of the intersecting streets A and B, each of these signalling units being provided with semaphore arms adapted to be selectively projected into signalling position so as to be seen when 'moving along either of. the cross streets A and B in the normal direction of tramo movement.

In the drawings two streets are shown intersecting in each instance, thereby forming iour corners necessitating the employment of four of the signal units at each intersection. It will be obvious, however, that when more than two .streets intersect at a commonV point more than four corners will be provided thereby necessitating the employment of Amore than-four of the signal units at each intersection. In each case a signal unit is provided upon each corner irrespective of the number of corners at the intersection,

each of these signal units being adapted to control traffic along the at the side of spaced walls. The shafts 3 and 4 are journailed in the bearings 6 and extend through the respective walls 7, suitable semaphore arms 8 being secured uponthe respective shafts at right angles to one another, so that v when the-shafts are simultaneously rocked one ofsaid semaphore arms will be in vertical position within `the casing of the signal unit, and the other semaphore arm 'will be in horizont-al position projecting outwardly from the casing of the signal unit, the said casing being provided with suitable slots 9 through which the semaphore arms maybe thus projected. X Rock arms 10 project Vlaterally from opposite 'sides of the shafts 3 and 4, these rock arms being shown as fixed relative to the shafts -by collars 11, preferably, integral with the respective rock arms and fixed upon Athe respectlve shafts 3 and 4.' Operating rods 12 are pivotally connected to the ends of the rock arms 10, as shown at 13, the

parts being so arranged that longitudinal movement of the operating rods within the casing of the signal unit in reverse directions will'rev'ersely rock shafts 3 and 4 to project one or the other of. the semaphore arms 8 outwardly into .signalling position whilethe other of thesem'aphore arms is concealed within the casing .1. These semaphore arms are adapted tosignal for traflc movement and for stopping of .tratlic movement respectively, and for' this purpose may have the words ,Go and Stop on the respective arms. l

'I he operating rods `12 are adapted to be rec1procated withiny the casing 1y kby a su1tabl e .electromagnet formed as a solenoid comprising upper and lower sections j14 and .15, the movable core of said solenoid being shown-at 16. ,The operating connection between the core 16 and the operating rods 12 may comprise a rod 17 extending" upwardly from the core 16 and, preferably, having a shdmgbearing 18 in the bearing bracket 5, the operating rods 12 ,being secured to the rod 17 by a yoke 19 fastened upon the rod 17 and ha-vlng the ends of the operating rods 12 pivoted thereto as shown at 20.

When the core of the solenoidis at either end of the solenoid and the opposite end section thereof' is. energized, the core will be moved within the solenoid to a position within said energized end of the solenoid and I the operating rods will accordingly be moved longitudinally within the casing 1 to rock the shafts 3 and 4 to change one of the semaphore arms from signalling position and to display the other semaphore arm in si alling position. The shafts 3 and 4 an the operating connections therefor are so arranged that When the shafts are rocked, thc rock arms 10 will be moved from a point at one side of the axis of the shafts 3 and 4 to a point at the opposite sideV of said axis, the rock arms being, preferably, yieldably held in either one of these positions by a spring v21 connecting the operating rods 12.

By this construction it will be seen that when the shafts 3 and 4 have been rocked to display one of the semaphore arms the parts will remain in the same position until the Solenoid is energized to rock the shafts 3 and 4 in the reverse direction for displaying the other semaphore arm.

One of the semaphore armsof a signal unit is', preferably, provided with a contact arm 22 arranged to close an electrical circuit through either a,contact 23 or a contact 24 depending upon v whether said semaphore arm is in signalling position or in concealed position. The contact arm 22 'is shown as carried by the Go semaphore arm and as closing a circuit through the contact 23 when in signallingposition and as closing a circuit through contact 24 when in concealed position. i The electrical circuits thus formed are for circuits through electrical lamps 25 and 26 respectively; y y

" These lamps "are shown as carried upon the lsignal unit, preferably, in a casing 27 in the front of'the casing of the unit, this casing being Vprovided with windows through which the lamps are adapted to show. The windows are shown at 28 and 29 and are, preferably, of different colored glass, as for example a yellow glass inthe window 29 forl the lamp 26 which is arranged to be illuminated when the Go signal is shown, and

llO

a red glass in the window 28 for the lamp 25 which is illuminated when the Stop signal is shown.

-Suitable electrical circuits, to be herein after described, are provided through the respective lamps 25 and 26, and through the respective. contacts 24 and 23, and through the contact arm 22 of the Go semaphore arm, so arranged that when the Go signal is shown the circuit through contact 23 will be closedfto illuminate'the lam 26, and when the Gro signal is in concea ed position and the stop signal is shown the circuit through the contact 24 will be closed to illuminate lamp 25.

An audible signal shown as a bell 30 is, preferably, provided in the casing 1 of the signal unit, this bell being shown as an electrical bell in an electrical circuit, to be hereso that when this circuit is'closed and the upper section of the solenoid is energized to display the Stop signal, the bell^ will be sounded. f

The signal units at the corners of a point of trailic intersection Aare arranged to be either locally controlled from the point of trailic intersection, or the signal units at several ,points of trailic intersection may be simultaneously controlled from a central station. Furthermore, the signalunits at one point of tratiic intersection may be selective` ly actuated so that all of the units are in Go^` signalling position, or so that all of the units are in Stop signaling position,

` or so that the units controlling traiiicin one o the cross directions of traflic are in, one of the signalling positions, and the units controlling traiiic in frthe cross direction oi .traiiic are in the opposite signalling position. When the signalling units are 1n this latter positionfcontrolling means are also provided for simultaneously reversing the signalling positions of the units. These controllin means are, preferably, electrically centro led, the 'electrical circuits and switches being diagrammatically illustrated in Figs. 7 to 14.

c .l In Fig. the circuits and controlling means forthe signal units, at a plurality of points of traiiic intersection either locally controlled or controlled from a central station, are illustrated, one set of electrical cir-` .y cuits passing through the upper sections 14 of the actuating solenoids of the .signalling units'V for energizing the upper sections of the actuating solenoidsto cause the Stop signal to be displayed, `and a second set of electrical circuits passing through the lower sections 15 of the solenoids to cause the Go signals to be displayed. For the purpose of illustration, four sig- 1 `nal units are shown at the point of traffic intersection, the units 31 and 33 controlling traffic in opposite directions along one street, and the units 32 and 34 controllingl trailic in opposite directions along the intersecting street. In Fig. 7 these signal units are shown with theunits 31 and 33 in Go poc sition to permit traiiic movement along one of the intersecting streets and the units32 and 34 in 5S-top position to prevent traiiic along the intersecting street. L The local controlling means for the sig` nalkunits is shown as comprising a switch 35having the contact 'armsj36 and 37 arranged to be thrown from the position shown in Figs. 7 and 8 to that shown in Figs. 9 and 10. The arm 36 of this switch, when in the position shown in Figs. 7 and 8, closes circuits thrcugh contacts 38, 39, 38b and 39?, and the arm 37 of the switch closes circuits through the contacts 39, 38, 39b and 38..

branch wires 41 and 42 respectively, so that when one of said switches is closed and the other switch is open, current will be supplied to" one of the arm-s ofswitch 35, and When the other of the switches in the branch wires 41 and 42 is closed and the irst inentioned of said switches 4is opened, current will beI supplied to the other arm of the,

Theco-ntacts 38, 38238b and 38 are electrically connected tro the upper end of the sect-ions 14 of the respective solenoids of the signal units 31, 32, 33 and 34 as by the wires 45, 45a, 45b and 45c respectively, and the contacts 39, 39a, 39b and 39c are electrically connected tothe lower end of the sections 15 of the solenoids of the signal units 31, 32,33 and 34 as by wires 46, 46a, 46b and 46c respectively. rThe adjacent ends of the sections 14- and 15 of the respective actuating solenoids of the respective sig` nal units 31, 32, 33 and 34 are electrically connected by wires 47 47a, 47b and 47c respectively, these wires being connected in a. common -wire 48 leading to the opposite side of the sourcebf electrica-l energy 50.

When it is desired to set the signal units in the position shown in ,Fig 7, the switch 35 is thrown to, the position shown in this' figure with the arms 36 and 37closing their respective contacts. The switch 44 is closed and circuits' are thereby, formed through the lower sections 15 of the actuating solenoidsfof the signal units 31 and 33 and Fthrough the upper sections 14 of the lactuating solenoids 32 and 34 to set the respective signal uni-ts in the position Go or Stop asshownkin Fig. 7. The circuits through these respectivey sections of the solenoids may be traced as follows: from the source of electrical energy 50, through wire 40, wire 42, switch 44, (the switch 43 in the opposite branch wire 41 from wire 40 being open) 'through switch arm 37 and contacts 39, 38a, 39b and 38c and Wires 46, 45a, 46b and 45c respectively, through the lower section 15 of the solenoid of thes-ignlal unit 31, through the upper section of Jthe solenoid of unit 32, through the lower sec-- tion ofthe solenoid of unit 33, and through the upper section of the solenoid of unit 34 respectively, through the respective branch wires 47 47a, 47b and 47 c to the. connecting wire 48` and thence to the opposite side of the source of electrical energy 50.

`When the switch 44 is closed, thus closing `the circuits as above traced` the signal arms of the respective signal units will be moved to the positionsshown in Fig. 7 and the signal arms will be held in these pbsitions until the ,opposite -ends ofi the respective solenoids are energized by the construction ofthe operating rods 12 andthe spring 21,'

`fas previouslsv described. It is therefore, only necessaryto close the switch44moinent'arily, ythe circuits closed .by this switch being opened'b f opening the switch as soon as the .signal various positions.` y

After the signal' units have been set in the position shown in Fig. 7v and^ traffic at a point of intersection has moved in one of the cross directions and,has been stoppedin the other cross direction, the opposite signal arm of the respective signal units is adapted to shown so ast-o permit movement of trailic and holding of traliica in the opposite cross directions. The respective signal units set in this position are shown in Fig. 8,

' the unit 31,being changed from Stop" posi# tionpto Go position and the remaining units having their signals similarly reversed. This reversing of kthe respective signals is accomplished by energizing the ends of the y'actuating solenoids opposite the ends previously energized so as torock the respective shafts 3 and 4. For this purpose the switch 35 is allowed to remain in the same position and the switch 44 is left open and the switch 43 is momentarily closed thereby. forming the following circuits through the respective actuating solenoids as shownv in Fig. 8. c, Fromy the source of electrical energy 50, through the line 40, the branch line 41, (theswitch 43 being closed) through the arm 36, the contacts 38, 39, 38b and 39 re spectively to the linesf 45, 46, 45b and 46, and lthence through the upper sections 14 of the actuating solenoids of the signal, units 31 and 33, and through the lower sec` tions 15 of the actuating solenoid of signal units 32 and 34 to the wires 47, 47, 47 and 47, and thence through the wire 48 to the opposite side of the source of electrical energy. V

The bells 30 of the respective signal units `are arranged to be sounded when the Stop signals are shown, and for this purpose each bell is shown as shunted across the circuit through theupper section 14y of the actuating solenoid. The connections for the bell being shown as a wire 51 from the respective wires 45. 45, 45b and 45 to one side o f the bell, and a wire 52 from `the opposite side vof the bell to the branch wires 47, 47, 471` and 47. f AThe circuits for thelamps 25 and 26 formed through the contacts 24 and 23 respectively, as previouslydescribem-these c'rcuits, preferably, comprising a wire 53 from the, respective branch wires 47, 47, 47

.and 47 having branch wires 54 andy 55 cong arms,` have been moved to their g-,tactarms 22 of the.Go semaphore arms are each connected to the wire40 leading to the source of electrical energy as by branch Wires V58, 58, 58 and 58 leading from` the respective contact arms and connecte-d b f a common wire 59 tothe wire 40, a switc 60 being, preferably, provided in the wire 5f) for throwing the electrical lamps into or out of operation.

By referring to Fig.7 it will be see that when the lo signal is shownthe lamp 26 will be illuminated, thecircuit through one of these lamps, say the lamp of the signal unit 31, being traced from the wire 48, wire 47, through wire 53,wireV 54, the lamp 26,

,wire 56, kcontact 23, vcontact arm 22 and wire y,switch 6() to the'wire 40.

The local switch 35 is also arranged to 'control means for causing all of the signals" at the point of trailic intersection to be set at Go, or all of the signals to be set at Stopy For ythis purpose the switch 35 is arranged to be thrown from the position shown in 7' and 8 to the position shown in Figs. 9 and 10, the arm 36 of the switch in this latter position making contact with contacts 61, 61, 61b and 61, and the arm 37 of the switch making contact with contacts 62, 62, 62b and 62. rl`he contacts 61, 61, 61b and 61 are connected to the wires 45, 45, 45"V and 45 respectively, and the contacts 62, 62, 62h, and 62 are connected to the wires 46, 46, 46b and 46 respectively, as by wires` 63, 63,` 63b and 63 and wires 64, 64", 64b and :64 respectively.

Referring, now, to Fig. `9 it will be seen that when the -switch 44 is closed (the switch 43 being open) circuits will be formed through the respective lower sections of the actuating solenoids to set the respective signals in Go position, these circuits being traced from the source of -electrical energy 50 through the switch 44, previously described, and thence through the arm 37,

By this arrangement the respectiveJ signal arms will be moved to Stop position, as previously described. I

The central station controlling means for the traffic regulators, means whereby oneserles of the traffic regulators at various points. of. traic intersection may be simultaneously controlled and another series of the regulators may be separately simultaneously controlled. For example all of the traffic regulators atthe point of trailic intersection along one of the streets A in Fig. 4 may be simultaneously controlled and all of the regulators along another of the streets A may beseparatelysimultaneously controlled. `In the following description the controlling means for the tra-flic regulator at one oint ofitratlic intersection will Y /be first descri dd, and the means whereby a plurality of. ysuch regulators along one of the streets may be simultaneouslycontrolled,

f fReferring to Fig. 7, a controlling switch 66, 66, 66 and 66 is provided in the circuit to the respective signal units 31, 32, 33 and 34, these switches being controlled byA either a switch 80 in the central station or a switch 105 or 106 therein, the switch 80'being employedwhen i't is desired to s'et the signal" units inlopposite signalling positions for the cross directions of tralic, as shown in Figs. 7 and 8, and the switches 105 and .'106 being employed when it is desired to set`a11 of the signal unitsl in Go and Stop positions respectively. v

Asv an instance of this arrangement, the switches 66, 66,"66'" and 66 are shown as comprising electro-magnets 7.0,70, 70 and 7 0- and 71, 71, 71 and 71 having the swing `ingcontact arm 7 2, 7 2, 72 and 7 2 arranged between the Inagnets` Hand adapted to be swung toward one or the other of` the magnets to close Athe contacts 7 3, 73, 73 andi? 3 yand 74, 74, 74hand 74` respectively when the ma. ets 70, 7 0", 70" and 70 and 71, 71, .71 an 71 are respectively energized. The contacts 7 3, 73, 7 3.and 73 of the respectile switches 66, 66, 66 and 66 are connected. to the wires 46, 46, 46 and 46 of the circuits thrpugh the sections 15 of the actuatpreferably, comprisesr ing solenoids, previously described, as by wires 7 5, 7 5, 75 and 75, and the contacts 74, 74, 74 and 74 of the respective vswitches areconnected as by wires 76, 76, 76 and 76 to the wires 45, 45, 45 and 45 of the circuits through the upper sections 14 ot the actuating solenoids, previously described. The swinging contact arms 72, 72, 72 and 72 of the respective switches are connected by a wire 77 to the wire 40 leading from the source of electrical energy 50, as previously described, a switch 78 being provided in the wire 77.

When it is desired to control ,theV signal units of a traffic regulator from the central station, the switch 78 is closed and, by means to be hereinafter described, the swinging contact arms 72, 72, 72 and 72 of the switches 66, 66, 66 and 66 are thrown to make/contact with either the contact points 73, 73, 73,and 73 or 74, 74, 74 and 74. l/Vhen it is desired to set thesignal units in the position shown in Fig. 7, that is with the units31 and 33 in the Go position and the units 32 and 34 inthe Stop position, the controlling means for the switches 66,

The switches 105 and 106 are connected to the generator as by the wire 107, and `the i switch 105- is arranged to make contact with the contacts 108, 108, 108b and 108, and the switch 10G is arranged to make-contact with the `contacts 109, 109, 109 and 109. The contacts 108, 108, 108 and 108 are connected respectively with the wires 85, 85, 85 and 85 as by the wires 110, 110, 110b and 110, and the contacts 109, 109, 109 and 109 are connected respectively with the wires 86, 86,-86 and 86 as by the wires 111, 111., 111'a`nd 111.

This arrangement is shown in Fig. 7, the controlling magnets for the use of one traffic regulator being shown at'C and similar controlling magnets for ,the units of another traffic regulator at one of the points of traffic intersection along the street A being shownl at D. The con-` nection from the 'wire 40 to this latter set of controlling magnets, is similar to,that reviouslydescribed, and the contactarms 2, 72, 72 and 72 ,actuated by these controlling magnets are arranged to make con-.,-A tact at either contacts 73, 73, 7 3 and 7 3 or contacts 74, 74', 74 and 74, as previously described. y ,y z

The respective( magnets of ,the group ot' f .controlling magnets D may be arranged inseries, in thecircuits to,the`respective sim-Y lilar'magnets of the group of controlling1V magnets C; -tFor this pur ose the magnets 71, 71, 71 and 71,of t e group D are shown as provided with wires 115, 115, 115

and 115 and wires 116, 116, 116 Land 116 'l connected to the respective wires 86, 86, 86 and 86, and the magnets 70, 70, 70 and 70 'of the group Dare shown as connected by wires 117, 117, 117 and 117 and 118, 118, 118 and 118 to the respective wires 85, 85, 85 and 85. By this arrangement it will be seen that closecbcircuits through any of the wires 85, 85, 85 and 85 and 86,' 86, 80 and 88 will cause simultaneous energizing of similar magnets of. the groups C and D. lt will be obvious that any number of such groups of controllingrmagnets for control- 4ling the traffic regulators at any number ot' points of traffic intersection may be arranged in series so as to be controlled by thisaine switches at the central station.

ssun'iing that all of the traffic regulators along one. of' the street-s A are jointly controlled from the central station, it may be found desirable. to similarly jointly control all of the traffic regulators along another of the parallel streets lA. Thisarrangement is alsoshow in Fig. 7, one of the switches 80 and 105 and 106 being provided for each group of traffic regulators which are jointl)q controlled. Thus the switches 80, 105 and 106 f'or one group of traffic regulators are shown at E and another group of switches 'are shown at F,-the arms 81 of these respective switches 80 being connected to thi` wire 9T leading to the contact point 05 b v branch wires 119 and 120 respectively` and the wire 98 leading to contact point 96 being connected to the arms82 of these respective switcliesby branch vwires 121 and 122, the wire 100 leading from the lgenerator 87 to the switches 105 andv 106 connecting these switches of the respectivecontrolling units E andi". lt will be obvious that as many of the controlling units, such as shown at E and F as may be found necessary, may be thus connected, the parts being solari'aiiged that the switches of the respective units will ,Lcontroll their respective traffic regulators.
